難題: macbook air三個partition不能安裝

jwschow

公司有部macbook air, 曾經被同事安裝bootcamp, 離職時咩都erase晒, 但係就只餘下三個partition.

一個係macOS個partition, 一個係recovery partition, 另一個應該係win partition.

當我地重新安裝, 用Option-Command-R 或Shift-Option-Command-R, 都係卡在同一點,
就係unmount唔到個partition. 我地曾經試過用terminal, 都係unmount唔到, 果partition應該
係recovery partition(但係唔應該要unmount, 應該因為有三個partition做成).

但係由於冇咗OS, 我地沒法處理. 我地亦曾經想用USB boot (OS X El Capitan)起, 但部機太舊,
唔support, 唔知仲有冇更好方法?

我最後用一隻CentOS 7的USB boot起, 用fdisk delete咗3個partition(原來有4個),
沒有了recovery partition.

再用一隻macOS USB boot起安裝. 呢隻USB boot係由另一架macboot係app store
download個OS, 再寫入USB.
